6. If your vehicle will be towing a trailer, load
from your trailer will be transferred to your
vehicle.
WARNING
•
Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire
overheating resulting in permanent
deformation or catastrophic failure.
•
Do not use replacement tires with
lower load carrying capacities than the
tires that were original equipment on
the vehicle because this will lower the
vehicle's GVW rating. Use only tires
with the correct load carrying capacity.
Consult your Volvo retailer for informa-
tion.
Tire specifications – terminology
The following is a glossary of tire-related
terms.
The tire suppliers may have additional mark-
ings, notes or warnings such as standard
load, radial tubeless, etc.
•
Tire information placard: A placard
showing the OE (Original Equipment) tire
sizes, recommended inflation pressure,
and the maximum weight the vehicle can
carry.
•
Tire Identification Number (TIN): A
number on the sidewall of each tire pro-
viding information about the tire brand
and manufacturing plant, tire size and
date of manufacturer.
•
Inflation pressure: A measure of the
amount of air in a tire.
•
Standard load: A class of P-metric or
Metric tires designed to carry a maximum
load at 35 psi [37 psi (2.5 bar) for Metric
tires]. Increasing the inflation pressure
beyond this pressure will not increase the
tires load carrying capability.
•
Extra load: A class of P-metric or Metric
tires designed to carry a heavier maxi-
mum load at 41 psi [43 psi (2.9 bar) for
Metric tires]. Increasing the inflation pres-
sure beyond this pressure will not
increase the tire's load carrying capabil-
ity.
•
kPa: Kilopascal, a metric unit of air pres-
sure.
•
PSI: Pounds per square inch, a standard
unit of air pressure.
•
B-pillar: The structural member at the
side of the vehicle behind the front door.
•
Bead area of the tire: Area of the tire
next to the rim.
•
Sidewall of the tire: Area between the
bead area and the tread.
•
Tread area of the tire: Area of the perim-
eter of the tire that contacts the road
when mounted on the vehicle.
•
Rim: The metal support (wheel) for a tire
or a tire and tube assembly upon which
the tire beads are seated.
•
Maximum load rating: a figure indicating
the maximum load in pounds and kilo-
grams that can be carried by the tire. This
rating is established by the tire manufac-
turer.
•
Maximum permissible inflation
pressure: the greatest amount of air
pressure that should ever be put in the
tire. This limit is set by the tire manufac-
turer.
•
Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that
are mounted on a vehicle at the factory.
This information can be found on the tire
inflation placard(s) located on the driver's
